HERMETICALLY-SEALED JAR.

Patented Nov. 2, i915.

' Application filed May 17, 1915. Serial No. 28,613.

' California, have made a new and useful Invention-to wit, a Hermetically-Sealed Jar;

and we do'hereby declare the following to be a full, clear, concise, and exact description of the same.

The invention relates to a hermetically sealed jar and contemplates improved means for readily removing the cover which seals the jar hermetically.

Referring to the accompanying drawing: Figure l is a vertical section of the upper part of a jar and its cover, embodying our invention, the cover being shown in her metically sealing position. Fig. 2 is a view somewhat similar to Fig. 1, showing the cover in the act of being removedto open the receptacle. Fig. 3 is a plan view of the jar with the cap thereon. Fig. 4 is a plan view of a modified form of our jar.

In the drawing 1 designates our improved jar receptacle which is open at the top and is provided with an annular external shoulder 2 near its top, and awide exterior flange 3 located'below said shoulder, and extending a considerable distance therebeyond. Upon the shoulder 2 rests a packing ring 4.

'A cap 5 is adapted to close the top of the receptacle 1. Said cap comprises a downwardly extending annular flange 6, an annular shoulder 7 extending outwardly from said flange and anannular flange extending downwardly from the outer part of said shoulder. In closing the top of the receptacle the shoulder 7 rests upon the packing ring 4 and the flange 8 against the ring,

1 whereby the jar is hermetically sealed. The

lower edge of the flange 8 rests slightly above the flange 3 to provide a space 9 therebetween to receive the blade of a table knife .10 or other tool. A lip 11 is preferably formed on the lower edge of the flange 8 which reinforces said edge andprovides a good engaging surface to be engaged by the blade edge of the said tool to lift thecap off the receptacle as will be described. In the modified jar shown in Fig. 4, the flange 3 extends only a short distance of the circumference of the receptacle 1.

In order to remove the cover from the receptacle, the side edge of the tool 10 is first inserted in, the space 9 so that said edge engages the lower edge of the flange 8 or the 11p 11 and the tool blade rests upon the receptacle flange 3 as shown in Fig. 1

of the drawing. The outer upper edge of the flange 3-serves as a fulcrum for the tool. Upon turning the blade of the tool transversely upon the outer upperedge of the flange 3 as a fulcrum, the side edge of the tool blade engages the lower extremitymf the flange 8 or lip 11 and lifts the side of the cap 5 adjacent the tool, bodily ofl the packing ring 4, the cap turning upon the ring 4: as a fulcrum at a point diametrically opposite the tool, there being suflicient clearance between the inner lower edge of the flange 8 and the exterior surface of the vertical receptacle wall and suiflcient clearance between the cap flange '6 and the exterior surface of the vertical receptacle wall to permit such turning movement of the cap. When one side of the cap is lifted bodily only slightly, by the tool, considerable portions of the flange 8 and shoulder 7 are disengaged from the packing ring 4 so that suflicient. air enters the top of the jar between the rmg 4: and the flange 8 of the cap to permit the cap to be readily removed from the receptacle.

- "."J e claim:

1. In combination, a receptacle, an exterior shoulder on said receptacle near the mouth thereof, a wide horizontal flange on the outside of Said receptacle extending considerably outwardly beyond said 'shoulder, a double-flanged cap. fitting over the mouth of said receptacle, a shoulder on said cap, a packing ring arranged between the receptacle shoulder and the cap shoulder, one of said cap flanges projecting downward fromv the outer part of said shoulder with its lower edge resting above said receptacle flange so as to provide a slight space between Said lower cap flange edge and said receptacle flange to receive a tool adapted to engage said lower cap flange edge, the outer upper edge of said receptacle flange being adapted to form a fulcrum for the tool so that said tool may lift said cap bodily at one side to remove said cap from the receptacle, there being sufiicient clearance between said cap flanges and the receptacle wall to permit such lifting movement of the side of the cap, and said cap when so lifted being adapted to turn on said packing ring as a fulcrum at a point diametrically opposite said tool.

2. In combination, a receptacle, a shoulder and a flange on the exterior of said recepproviding a slight space between the lower extremity of said cap flange and said receptacle flange for the insertion of a tool, the outer upper edge of said receptacle flange forming a fulcrum for the tool so that the tool may lift said cover bodily at one side to remove said cover from the receptacle there being sufficient clearance between said cap flanges and the receptacle Wall to permit such lifting movement of 'the side of the.

cap.

3. In combination, a receptacle, an annular shoulder and a flange on the exterior of said receptacle near the mouth thereof arranged one above the other, said flange extending considerably outwardly beyond said shoulder, a double flanged cap fitting over the mouth of the receptacle, an annular shoulder on said cap, a packing ring arranged between said receptacle shoulder and said cap shoulder, one of said cap flanges projecting downwardly from the outer-part of said cap shoulder'but with its lower extremity resting above said receptacle flange and providing a space between the lower extremity of said cap flange and said receptacle flange for the insertion of-a tool, an

annular flange on the lower extremity of said cap flange to be engaged by the too], the outer upper edge ofsaid receptacle flange forming a fulcrum for the tool so that the tool may lift said cap bodily at one side to remove said cover from the receptacle there being suflicient clearance between said cap flanges and the receptacle wall to permit such lifting of the Side of the cap.

4. In combination, a receptacle, a shoulder and a flange on tllGGXtBI'lOI of said receptacle near the mouth thereof arranged one above the other, said flange extending considerably outwardly beyond said shoulder, a double flanged cap fitting over the mouth of said receptacle, a shoulder on said cap, a

packing ring arranged between said receptacle shoulder and said cap shoulder, one

of said flanges projecting downwardly from the outer part of said cap shoulder with its lower extremity resting slightly above said receptacle flange and providing a slight space between the lower extremity of said 'cap flange and said receptacle flange for the the cap so that its edge may lift said cap bodily at one side, said cap being adapted to turn on said packing ring as a fulcrum at a' point diametrically opposite said tool when said tool lifts one side of the cap. 5. The combination of a receptacle, a cap anda packing adapted to seal the mouth of the receptacle air tight, the receptacle being provided with an exterior outwardly projecting flange so located with relation to the lower edge of the cover that a knife blade or other suitable instrument may be readily inserted between the lower edge of the cover and the outwardly projecting flange and turned on said flange as a fulcrum for the purpose of lifting the cover bodily at one side off of the jar there being suflicient clearance between said cap flange and the receptacle wall to permit such lifting of one side of the cap. I

6. The combination of a receptacle, a cap for hermetically sealing the mouth of said its side edges engaging the lower edge of said cap to lift the cap bodily at one side with relation to the receptacle there being suflicient clearance between said cap flange and the receptacle wall to permit such lifting of one side of the cap.

In testimony whereof, we have hereunto set our hands at San Francisco, California, this 10th day of May 1915.
